Actually gauge is the easiest thing to change in modern LRV's especially if your non standard gauge is larger than standard or "Stevenson Gauge". All you have to do is insert a spacer that increases the distance between the flanges (wheels) and the body of the Truck or Bogie its really very easy. There are lots suppliers of Toronto, Pennsylvania (Philadelphia and Pittsburgh), and Boston Kits out there. All these transit operations have significant subway and or LRV operations with non standard gauge. In most cases there is no axel going all the way through the truck or bogie with modern low floor LRV's which allows significant storage space, in some cases like with the standard Russian Gauge of 1581 mm, it actually makes construction easier because there is a much more significant amount of space to add equipment.
In the case of all LRV's that been sold in North America until Toronto and Ottawa started their contracts, the design has been the standard 70% low floor LRV. The 70% low floor LRV has no low floor over the trucks but a raised platform, which normally has a interior ramp structure leading to it from the low floor sections of the vehicle. Toronto's Streetcars have had their production issues because the workers at both of Bombardier's North American LRV production sites, the Thunder Bay Assembly Plant and the Mexican Parts Fabrication Plant in Mexico have never built parts for or assembled a 100% Low Floor LRV before. The 100% Low Floor LRV is very common in Europe and Bombardier's European production facilities but not in North America. Unfortunately, it is the much more exacting design and production standards needed to build the 100% Low Floor LRV that is the problem. Our Bombardier workers have never done it before. Its like switching from building Business Jets and Commuter Aircraft to International medium-ranged Jet Airliners. They both fly but one is a lot more difficult, complicated and expensive to build as well as the reason so few companies around the world still make them. Bombardier even told both local and provincial politicians and managers at the TTC back in 2008 that, they would have preferred that Toronto's Streetcars be built in Europe to avoid this problem. Unfortunately, you can't tell people and politicians that, "sorry, your local workers just aren't good enough and need to be retrained before they build these types of LRV's in Ontario". No politician or TTC manager is going to admit to the press that we warned years ago that this would happen by Bombardier. The increased production that Bombardier is promising I bet, will be done via a European plant building key parts of the Toronto Streetcars and extra assembly work done in Ontario.
Toronto's Streetcars also have production complications because it is the only 30+ metre long, 100% low floor LRV in the world that is not limited to 25 metre radius turns at commercial speeds. Toronto Streetcars must negotiate 10.5-11 metre radius curves at or near commercial speeds. This has greatly complicated design factors. This particular design requirement was the reason Siemens Transportation North America, did not bid on the Toronto project, even when it was put up twice, for bidders. Most LRV companies do not want to go below the 25 metre turning radius requirement.
This by the way, was the real reason Siemens Transportation North America's CEO and CFO were fired, by the Siemens International Chairman back in 2008. They blew off the 204 LRV order for Toronto streetcars plus the options on possibly 300 more standard LRV's ordered for Ontario LRT lines, because they didn't want to alter existing production facilities to fit design changes needed so the Toronto Streetcars could make the tight turns at or near commercial speeds. Siemens had just completely finished a seriously needed corporate restructuring that saved the company from death. Many side businesses were sold off and other company product divisions simply disappeared. Also, the Transportation part of the company had lost a lot of LRV market share in Europe because of many design faults in the European standard Combino Class LRV. It was reported that the Chairman of Siemens International was so ticked off at his junior CEO and CFO in North America he responded that, for 204 LRV's and possibly hundreds more for other operations in Canada, all in the core territory of one of his biggest transportation competitors Bombardier, he would build them a whole F*ing factory.
Ottawa's LRV's also 100% Low Floor, had the floors and Trucks built in Europe at one of the Alstom LRV plants in France, then had exterior body and interior sections added at the their Platsburgh New York facility. Final vehicle assembly of the 48 metre long, 4 section Alstom Citadis Spirit LRV's are being done at Belfast Yards in Ottawa, right now as we speak!
